_Symptoms_: New growths, causing swelling and enlargement of the part of the body in which they appear. A tumour, unlike an abscess, generally forms slowly, and is at first usually not painful, and moreover, is not accompanied during the early stages by a rise of temperature as is found when an abscess is forming. _Treatment_: It is seldom that a tumour of any kind can be reduced or removed except by a surgical operation. I have sometimes thought that gently rubbing the tumours formed on the milk glands, especially when small, daily for some time with iodine vasogen has checked their growth. Directly a tumour has been diagnosed, unless the patient is a very old one, it is best to have it removed before it has developed into a large growth; the operation, unless the tumour is situated in the neck, is a simple one, and the wound, with ordinary aseptic precautions, heals in seven or eight days. Of course there are some exceptions, as, when the tumour is a cancer or some other malignant growth, it is not always advisable to sew the wound up after operation, but then of course it takes much longer to heal. =Ulcers=: _Symptoms_: These are unhealthy wounds or sores left after decay or destruction of some superficial parts of the body. _Treatment_: Keep them clean by sponging two or three times a day with Pearson’s fluid—one teaspoonful to half a pint of water. For a day or two apply either hot linseed-meal poultice dusted over with powdered charcoal, or a piece of lint soaked in a saturated solution of boracic acid, placed over the wound and covered with oil-silk, then bandage. When the wound looks cleaner, healthier, and discharges less, and there are signs of healing by the formation of new skin around the edges of the wound, simply cover it over with some carbolic gauze squeezed out in a solution of boracic acid, and apply a bandage. When an ulcer is healing very slowly, lint dipped in the following lotion and applied to the ulcer stimulates healthy action and healing:— _Recipe: The Lotion_: Tincture Calendula, 3 drachms. Sulphate of Zinc, 1 scruple. Water to 6 ounces. Mix. Apply as directed two or three times a day. In some cases dusting the wound over with a powder made with one part of iodoform mixed with eight parts of boracic acid. Amyloform is also another good healing powder. It is necessary to keep the dog’s tongue away from it, otherwise he is continually licking off the new skin as it forms. =Uræmia=:
